Abstract

Mathematical modelling was carried out in order to study the kinetics of the sub- and supercritical fluid extraction from turmeric, using carbon dioxide with either ethanol or isopropyl alcohol and their mixture (1:1 v/v) as co-solvents. The variables studied were pressure, solvent flow rate, co-solvent percentage and bed height to bed diameter (H-B/D-B) ratio. Using the previously obtained experimental data, four mathematical models were evaluated in the present work to identify those that accurately fit the overall extraction curves. The models of Goto and Sovova were the ones that best correlated most of the experimental overall extraction curves obtained for turmeric extraction, even when using pressurized liquid solvent mixtures.
